Phys.org / Bacteria that generate electricity: How a shellfish-based gel could monitor wastewater and food
Microbial bioelectronic sensors use living bacteria that can create an electrical signal in response to the presence of a target substance, or analyte. These types of sensors offer many advantages over other types of biosensors ...
Phys.org / Why simulating an entire cell cycle took years, multiple GPUs and six days per run
By simulating the life cycle of a minimal bacterial cell—from DNA replication to protein translation to metabolism and cell division—scientists have opened a new frontier of computer vision into the essential processes ...
